Gordon M. Williams (born 1934) is a Scottish author. Born in Paisley, he moved to London to work as a journalist. He has written for television and is the author of over twenty novels including From Scenes Like These (1969), shortlisted for the Booker Prize in 1969, Walk Don't Walk (1972) and Big Morning Blues (1974). Other novels include The Camp (1966), The Man Who Had Power Over Women (1967) and The Upper Pleasure Garden (1970).

In 1976 film producer Harry Saltzman hired Williams to re-write the script for The Micronauts. Although the film was never made, Williams' novelization was published in 1977; he subsequently wrote two sequels.

While working as commercial manager of association football club Chelsea, he renewed his collaboration with Venables, resulting in four co-written novels. From the novels grew the 1978 TV series Hazell, which the pair co-wrote under the shared pseudonym P. B. Yuill. Under the name "Jack Lang", Williams also wrote paperbacks "for £300 a time".[1]
